Denton County property tax: rates, assessments, and how to appeal

Last updated 2026-07-09

How does Denton County property tax work?

Denton County property tax is not a single charge. It is a stack of levies from overlapping taxing units: Denton County itself, your school district (Denton ISD, Lewisville ISD, Carroll ISD, and others), your city or town, any municipal utility districts, and sometimes a hospital or community college district. Each unit sets its own rate. The appraisal district multiplies your assessed value by the combined rate to produce your annual bill.^[1]

The Denton Central Appraisal District (DCAD) is the agency that sets value. It is a separate entity from the county government and from the taxing units that collect the money. DCAD appraises every property as of January 1 each year, mails notices in April or early May, and handles protests. The county Tax Assessor-Collector then sends the actual bills in October, due by January 31.^[2]

That split matters. Your fight, if you have one, is almost always with DCAD, not with the county commissioners. The commissioners have no power over your assessed value. They only set the county's rate.

For how other large Texas counties run the same machinery, see our guide on bexar county property taxes. The mechanics are nearly identical under Texas law.

What are the current Denton County property tax rates?

Tax rates in Denton County swing hard by location, because your total rate is the sum of every taxing unit with jurisdiction over your parcel. The county's own rate for fiscal year 2024 was $0.189485 per $100 of assessed value, down from prior years under the compression rules in Texas Senate Bill 2.^[3]

School district rates dominate your bill. Here is a representative snapshot of 2023 adopted rates per $100 of assessed value for major taxing units in Denton County. Rates change annually, so verify current figures at DCAD or each entity's website.^[3][4]

Taxing Unit	Approx. 2023 Rate (per $100)
Denton County	$0.1895
Denton ISD	$1.1169
Lewisville ISD	$1.2129
Carroll ISD (Southlake)	$1.1392
City of Denton	$0.5607
City of Flower Mound	$0.3374
City of Lewisville	$0.4451
City of Frisco (portion in Denton Co.)	$0.4466

Live in an unincorporated area and you skip the city rate entirely, which can shave 30 to 50 cents per $100 off your combined rate. A home assessed at $400,000 in unincorporated Denton County in the Denton ISD zone might face a combined rate around $1.31 per $100, producing a gross bill near $5,240 before exemptions.^[3]

For homeowners in Virginia counties curious how rates compare, our coverage of loudoun county property tax and montgomery county property tax shows how assessment-based systems differ from the Texas annual appraisal model.

How does the Denton Central Appraisal District set your assessed value?

DCAD uses mass appraisal, not individual inspections. Appraisers group similar properties into neighborhoods and tune a valuation model to recent comparable sales. Texas Tax Code Section 23.01 requires that all property be appraised at its "market value" as of January 1, defined as the price it would sell for in an arm's-length transaction on that date.^[5]

In practice, DCAD leans on three approaches: sales comparison (what similar homes sold for), cost (what it would cost to replace the structure, minus depreciation, plus land value), and income (for rental or commercial property, the capitalized net operating income). Homes are almost always valued by sales comparison.^[5]

Mass appraisal makes predictable mistakes. If your neighborhood had few sales in the prior year, the model may reach for sales from a broader pool that ignore your street's actual conditions. If your home has a functional problem (outdated floor plan, road noise, foundation repairs, a busy commercial neighbor) that never shows up in the sales data, the model misses it. Those misses are your best argument on appeal.

You can search your property's details and current assessed value on the DCAD property search portal. The record shows land value, improvement value, exemptions applied, and the comparable sales DCAD used to support the number. Pull that data before you do anything else.^[2]

To understand how property assessment value is calculated more broadly, including the difference between assessed value, appraised value, and taxable value in Texas, that guide covers the terminology clearly.

What exemptions are available for Denton County homeowners?

Texas has several exemptions that cut the taxable value of your home, and Denton County homeowners who are not enrolled in the right ones are leaving money on the table.

The homestead exemption is the big one. Under Texas Tax Code Section 11.13, every school district must offer a $100,000 homestead exemption on your appraised value for school tax purposes starting in the 2023 tax year, up from $40,000 before Proposition 4 passed in November 2023.^[6] Counties may add an optional exemption up to 20% of appraised value (minimum $5,000). The City of Denton, Denton County, and most other local entities offer their own percentage exemptions on top of the school exemption. File one homestead application with DCAD to claim all of them at once. You file once, and it carries forward automatically.

The age-65-or-older exemption knocks another $10,000 off the school district taxable value under state law, plus whatever each local entity offers. The bigger benefit is the freeze: it locks your school district tax at the dollar amount you paid the year you turned 65 and applied. That freeze (a tax ceiling) holds for as long as you own and occupy the home.^[5]

The disability exemption mirrors the over-65 benefits and also creates a school tax ceiling. You must qualify as disabled under the Social Security Administration's definition.

Veterans and surviving spouses may qualify for a partial or 100% exemption depending on their disability rating from the U.S. Department of Veterans Affairs. A 100% disabled veteran pays zero property tax on a primary residence in Texas.^[5]

Apply for exemptions at DCAD's office or through its online portal. The deadline to file most exemptions is April 30 of the tax year, though a late homestead application filed before the appraisal roll is certified (usually around July) may still get accepted.

What is the 10% homestead appraisal cap and how does it protect you?

Texas caps how much DCAD can raise the appraised value of your homestead in a single year. Under Texas Tax Code Section 23.23, the appraised value of a qualified homestead cannot climb more than 10% above the prior year's appraised value, no matter what the market does.^[5]

This cap is not automatic protection when you just bought the home. It resets when a property changes hands, so new buyers in fast-appreciating markets often eat a sharp jump in the first or second year. After that, the 10% ceiling takes hold and the appraised value can only creep.

One nuance people miss: the cap applies to appraised value, not to your tax bill. Taxing units can still raise their rates, so your bill can climb even when your capped value does not.

DCAD also keeps a separate market value on record that can sit above your capped appraised value. State law requires that split. If you move and the cap resets, the new appraised value jumps toward that market value, not toward the old capped number. Keep that in mind when you estimate future tax on a home you are thinking about buying.

For a wider look at how assessment caps work across states, the values assessment guide explains the mechanics and trade-offs.

When is the deadline to protest your Denton County property tax assessment?

The protest deadline is May 15 or 30 days after DCAD mails your notice of appraised value, whichever date is later.^[5] If May 15 lands on a weekend or holiday, the deadline moves to the next business day.

Do not wait for the notice if you already know your value went up. You can file any time after January 1 and before the deadline, even without a formal notice in hand. Protest forms are on DCAD's website.

Miss the deadline and your options shrink fast. A late protest is allowed only in narrow cases: a clerical error in the records, a property left off the appraisal roll, or a property appraised above its market value on the date the tax lien attached (January 1), backed by a deed or appraisal completed within the same tax year. Not checking your mail is not grounds for a late protest.

Here is a quick timeline of the Denton County property tax calendar:

Date	Event
January 1	Appraisal date; ownership and exemption status determined
April 1	DCAD begins mailing appraisal notices
April 30	Deadline to file most exemption applications
May 15 (or +30 days from notice)	Protest filing deadline
May-July	Informal hearings and ARB hearings
~July	Appraisal roll certified
October	Tax bills mailed by county Tax Assessor-Collector
January 31	Tax payment due (no penalty)
February 1	Penalties and interest begin on unpaid balances	[2][5]

How do you file a Denton County property tax protest?

Filing a protest with DCAD is simple. You submit a Notice of Protest form (Comptroller Form 50-132 or DCAD's equivalent), check the box for "value is over market value" plus any other grounds that fit, and get it in before the deadline. File online through DCAD's iFile system, by mail, or in person at the DCAD office in Denton.^[2]

After you file, DCAD schedules an informal hearing. This is a one-on-one talk with a staff appraiser, not a formal trial. Most protests that arrive with real evidence get settled at this stage, according to the Texas Comptroller's annual property tax report, though DCAD's specific settlement rate moves year to year.^[7] Bring your ammunition: recent comparable sales, a licensed appraisal if you have one, photos of condition problems, repair estimates, or any factual errors you found in DCAD's records (wrong square footage, wrong bedroom count, features that do not exist).

If the informal hearing does not land a settlement you can live with, your case goes to the Appraisal Review Board (ARB). The ARB is a panel of independent citizens, not DCAD employees. You present your evidence, DCAD presents theirs, and the panel decides. You do not need a lawyer or agent for an ARB hearing, though you can bring one.

If the ARB rules against you and you still think your value is wrong, you can appeal to district court, request binding arbitration, or take the case to the State Office of Administrative Hearings (SOAH). Those paths carry cost and complexity, so most homeowners stop at the ARB unless the money in dispute is large.

Doing this yourself works. TaxFightBack's appeal kit gives you the exact evidence templates, comp-selection rules, and hearing scripts used to argue residential protests solo, so you keep 100% of any reduction instead of handing a slice to a contingency agent.

For property tax records research, including how to pull DCAD sales data and match it against your assessment, that guide walks the process step by step.

What evidence wins a Denton County property tax protest?

The strongest single piece of evidence is comparable sales that point to a lower value. A "comp" is a property that sold at arm's length within roughly six months of January 1, in your neighborhood, with similar size, age, condition, and features. If three or four comps cluster around a value 10% or more below DCAD's number, you have a winnable case.

Here is where homeowners blow it. They cherry-pick comps that are obviously worse (smaller, rougher, further away) hoping to drag the value down. Appraisers see this all day, and it torches your credibility. Pick the most similar homes you can find that still support your argument. Being honest about the limits of your own comps actually helps you in the hearing room.

Factual errors in DCAD's records are often easier to win than value disputes. Read the property card line by line. If the record says 2,400 square feet and your home is 2,150, that error probably padded your value by 10 to 15%. Same story for phantom bathrooms, a finished basement that never existed, or a pool filled in years ago. Get the builder's floor plan, a tape measure, or a licensed appraiser to document the gap.

Photos of condition problems (deferred maintenance, foundation cracks, dated systems) carry weight when you pair them with repair estimates on contractor letterhead. Go past the pictures. Show what the fix costs, because that cost is the bridge from your condition to a lower value.

For more on building a comparable sales argument, including the comp radius and time rules Texas appraisers use, the evidence-and-comps section covers the methodology.

The Texas Comptroller's Property Tax Assistance Division publishes the Appraisal District Director's Manual, which lays out the standards appraisers must follow, and it is a handy reference when you build your argument.^[7]

How does the Denton County property tax assessment search work?

The DCAD property search portal lets you look up any property in Denton County by owner name, address, or account number. The search is free and open to the public, no login required.^[2]

A typical record shows the owner of record, the legal description, the land area, the improvement square footage and year built, DCAD's split between land value and improvement value, exemptions currently applied, the prior three to five years of assessed values, and the comparable sales the appraiser used to support the current number.

That list of DCAD's own comps is gold. If the comps they leaned on are larger than your home, in better shape, or sitting in a nicer pocket of the neighborhood, you can argue their own evidence overstates your value. You are cross-examining them with their own file.

Watch the "neighborhood code" assigned to your property. DCAD groups properties into valuation neighborhoods, and every home in the same code gets calibrated to the same model. If your code looks wrong (say, your modest 1980s ranch is lumped with newer homes across a major road), that can be a valid protest ground.

This same search approach works in other counties. For comparison, the property-tax-lookup guide explains what to look for in any county's public appraisal portal.

What happens after a Denton County property tax appeal is decided?

If DCAD adjusts your value at the informal hearing, they issue a written settlement agreement. Sign it and the new value locks in for that tax year. The reduction flows automatically to every taxing unit. You do not have to notify each one.

If the ARB issues an order in your favor, DCAD must adjust the roll within a few days. Again, the change spreads to all taxing units on its own.

Already paid your tax bill (or made an installment) before the appeal wrapped up? You are owed a refund of the overpayment. Tax Assessor-Collector offices in Texas must issue refunds within 60 days under Texas Tax Code Section 31.11, though in practice it can run a little longer.^[5]

One thing many homeowners miss: a reduction this year does not carry into next year. DCAD re-appraises every January 1. Your value can bounce right back up if the market supports it. Winning a protest is a one-year fix unless the underlying market genuinely softens.

For a full picture of what comes next, the after-the-appeal articles on this site walk through refund timing, how to handle a split decision, and when it makes sense to push a case further.

How do Denton County property taxes compare to other Texas counties?

Texas has no state income tax, and the state funds a big share of public education through property taxes, which pushes Texas effective property tax rates among the highest in the country. The Tax Foundation ranked Texas 7th highest for effective property tax rates on owner-occupied housing in 2023, at roughly 1.60% of market value statewide.^[8]

Within Texas, Denton County sits in the mid-to-upper range. Its effective rate generally runs higher than counties in West Texas (lower land values, different school funding needs) and lands close to Tarrant and Collin counties, its immediate neighbors. Harris County (Houston) and Travis County (Austin) have faced similar pressure.

Bexar County (San Antonio) tends to run slightly lower effective rates than Denton County, partly because of different school district funding structures. For a full comparison, see bexar county property taxes.

Outside Texas, Denton County's rates look steep next to California (often below 0.8% thanks to Proposition 13 caps) or Nevada's Clark County (roughly 0.5 to 0.7% effective). See the clark county property tax breakdown for how that system works by contrast.

The Texas Comptroller publishes annual reports on appraisal district performance and effective tax rates across all 254 counties, which is the most reliable source for cross-county comparison.^[7]

Are there special programs for seniors, disabled homeowners, or people struggling to pay?

Yes, and these programs are underused. Past the standard exemptions covered earlier, Texas offers a deferral program that deserves more attention.

Under Texas Tax Code Section 33.06, any homeowner who is 65 or older, disabled, or a disabled veteran can defer payment of property taxes on the homestead indefinitely.^[5] Interest accrues at 5% per year on the deferred amount (versus the standard 12% penalty rate for nonpayment), and no foreclosure can happen on a deferred homestead. The deferred taxes come due when the property is sold or stops being the owner's homestead. File a deferral affidavit with the county Tax Assessor-Collector.

Installment plans are open to homeowners who qualify for the over-65 or disability exemption. They can pay in four equal installments due February 1, April 1, June 1, and August 1 without penalty.

Surviving spouses of disabled veterans and of first responders killed in the line of duty may qualify for a 100% exemption under Texas Tax Code Sections 11.131 and 11.132. These get missed because they need a separate application.

The Denton County Tax Assessor-Collector's office lists contact information for its Taxpayer Assistance division if you are in financial hardship and want to talk through options before penalties start.^[9]

Frequently asked questions

When are Denton County property tax bills mailed and when are they due?

DCAD certifies the appraisal roll in July, and tax bills are typically mailed by October 1. Payment is due by January 31 of the following year with no penalty. Starting February 1, a 6% penalty plus 1% interest kicks in, and the rate climbs monthly. If you miss February 1, pay as fast as you can because interest compounds.

How do I apply for a homestead exemption in Denton County?

File a Residence Homestead Exemption Application (Comptroller Form 50-114) with the Denton Central Appraisal District. Submit it online through DCAD's portal, by mail, or in person. The deadline is April 30 of the tax year, though DCAD may accept late applications before the roll certifies. You apply once; the exemption renews automatically while you own and occupy the home.

What is the Denton County property tax protest deadline?

The deadline is May 15 or 30 days after DCAD mails your notice of appraised value, whichever is later. If May 15 falls on a weekend or holiday it shifts to the next business day. You can file before receiving a notice if you already know your value increased. Missing the deadline almost always means you lose your right to protest for that tax year.

Can I protest my Denton County property tax assessment without a lawyer or agent?

Yes. Texas law explicitly lets homeowners represent themselves at both the informal hearing with DCAD staff and the formal Appraisal Review Board hearing. Most residential protests settle at the informal stage. Bring your comparable sales data, photos of condition issues, and any factual errors you found in DCAD's property record. A contingency agent takes a share of your savings; doing it yourself costs nothing.

What is the homestead appraisal cap in Denton County?

Under Texas Tax Code Section 23.23, the appraised value of a qualified homestead cannot rise more than 10% per year, regardless of market conditions. The cap resets to market value when the property changes ownership. It applies to appraised value, not to your tax bill, so rates can still push your bill higher even when the cap holds your value steady.

How do I search for a Denton County property tax assessment online?

Use the property search tool on DCAD's website. Search by owner name, property address, or account number. The record shows your current assessed value, prior years' values, the exemptions applied, the land and improvement breakdown, and the comparable sales DCAD used to support your value. No login or fee required. Pull the comparable sales list early; it tells you exactly what DCAD's case is.

Does Denton County offer a senior citizen property tax freeze?

Yes. Homeowners age 65 or older who apply for the over-65 exemption receive a tax ceiling (freeze) on the school district portion of their bill. The dollar amount of school taxes you owe is capped at whatever you paid the year the ceiling was set. If you move, the ceiling transfers proportionally. The freeze does not apply to city or county taxes, which can still rise.

What is the Denton County property tax rate for 2024?

The county's own 2024 adopted rate was $0.189485 per $100 of assessed value. Your total rate also includes school district, city, and any special district rates. Combined rates for most Denton County residents fall between roughly $1.70 and $2.50 per $100 of assessed value depending on which city and school district you are in. Verify current rates at each taxing unit's website.

What grounds can I use to protest my Denton County appraisal?

The most common and effective grounds are: value is above market value, value is unequal compared to similar properties, or the property is described incorrectly in DCAD's records. The unequal appraisal argument (your home is taxed at a higher percentage of market value than comparable homes) is a separate and powerful Texas-specific ground established in Texas Tax Code Section 41.43.

How long does a Denton County property tax protest take?

Informal hearings are usually scheduled within four to eight weeks of your protest filing, often by phone or video. If you settle there, the whole thing can wrap in under two months. ARB hearings take longer and typically run through June and July. If you appeal an ARB decision to district court or arbitration, expect six months to over a year.

Can I get a property tax refund if I win my Denton County protest after paying?

Yes. If you paid your bill before the protest resolved and your value is later reduced, you are owed a refund. Under Texas Tax Code Section 31.11, the collecting unit must send your refund within 60 days of the correction being certified, assuming the refund exceeds $1. Interest is not paid on overpayments returned within that window.

Does Denton County have a property tax deferral for seniors?

Yes. Homeowners who are 65 or older, disabled, or a qualifying disabled veteran can file a deferral affidavit under Texas Tax Code Section 33.06 and legally defer paying property taxes on the homestead. Interest accrues at 5% annually on the deferred balance. The taxes come due when the home is sold or stops being the owner's homestead. No foreclosure can happen during an active deferral.

How does Denton County property tax compare to what I would pay in Virginia or Maryland?

Texas effective rates generally run higher than Virginia and Maryland on a straight percentage basis, but Texas has no state income tax, which changes the overall burden comparison. Loudoun County, Virginia's effective property tax rate runs around 0.9 to 1.1%, while Denton County residents typically see effective rates of 1.8 to 2.2%. Maryland's Montgomery County effective rate is roughly 0.9 to 1.2%, also lower than Denton County.
